Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national stage application of International Application No. PCT/US2019/040719, filed on Jul. 5, 2019, which application claims priority to Provisional Application No. 62/694,431, filed on Jul. 5, 2018, which applications are hereby incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to systems and methods for decentralized forecasting to optimize power grid operation.

BACKGROUND

Traditional transmission grid operation takes a centralized approach. Measurements from the power grid are gathered and transmitted to a central control. The central control processes the data and formulates a plan on how optimize power production. The central control will then transmit instructions to all the power grid components in order to implement the plan.

However, the increasing complexity and scale of power grids have made the traditional approach no longer feasible. The rise of Distributed Energy Resources (DERs), such as solar panels and wind turbines, has increased the erratic nature of power grids due to the unreliability of these energy sources. Today's power grids need sub-minute control and optimizations, and the latencies associated with a centralized approach do not allow for such precision. The traditional techniques are impossible to implement with the scale of today's transmission grid systems.

DETAILED DESCRIPTION OF THE DRAWINGS

While the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the figures and will be described herein in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives consistent with the present disclosure and the appended claims.

References in the specification to “one embodiment,” “an embodiment,” “an illustrative embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may or may not necessarily include that particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

The disclosed embodiments may be implemented, in some cases, in hardware, firmware, software, or any combination thereof. The disclosed embodiments may also be implemented as instructions carried by or stored on a transitory or non-transitory computer-readable storage medium, which may be read and executed by one or more processors. A computer-readable storage medium may be embodied as any storage device, mechanism, or other physical structure for storing or transmitting information in a form readable by a compute device (e.g., a volatile or non-volatile memory, a media disc, or other media device).

In the drawings, some structural or method features may be shown in specific arrangements and/or orderings. However, it should be appreciated that such specific arrangements and/or orderings may not be required. Rather, in some embodiments, such features may be arranged in a different manner and/or order than shown in the illustrative figures. Additionally, the inclusion of a structural or method feature in a particular figure is not meant to imply that such feature is required in all embodiments and, in some embodiments, may not be included or may be combined with other features.

The presently disclosed systems and methods allow for the optimization of an electrical grid without relying on a central control to perform calculations. In particular, the present disclosed systems and methods allow for decentralized forecasting and localized optimization. Each component in the electrical grid may be equipped with a compute device. The compute device allows each component to determine its own forecast and communicate with other components having such capabilities. The components may “negotiate” with one another using various machine learning techniques in order to locally optimize that section of the power grid. Decentralizing the forecasting and optimization processes decreases latencies and cost of the power grid system. As used in the present disclosure, “optimize,” “optimization,” and similar terms are not intended to require that a truly optimal state be achieved or even sought; rather, such terms are intended to convey any level of relative improvement of (or even an attempt to improve) the condition or state being “optimized.”
